It was like the ghost of racing past. I knew it was going to come down to that. ... I can't believe I lost, but Mark is the guy to beat when you're racing IROC.

It's something I'll remember forever, racing Mark Martin for the IROC win. It was one of those great battles, where I knew if I couldn't hit him, knew I couldn't touch him, and I wanted to race him clean.

I just always dreamed of racing cars, but I didn't think I could do it as a living.

This 51 Phoenix Racing team, I love them to death. They've got my back, I've got theirs.

I am grateful to Penske Racing for six very productive years. Together we won a lot of races - 16 in all. I'm proud that we won on a variety of tracks.

Over the Thanksgiving holiday I took time to reflect on what is most important to me and realized I need to find a way to put the fun back into racing.
